Good day all,
What is your experience using PVC SCH40 pipe on standpipe systems? eg for hose reels?
Although NFPA 14 does not reject it's use, I am concerned about its heat resistance.
Thanking you in advance.
So what is your section reference out of NFPA 14 and which edition,,,
That shows PVC is allowed
I checked NFPA 14, 2019 Edition. I did not see anything stating PVC is not allowed. Section 4.2.6 states “Other types of pipe or tube investigated for use….. shall be permitted where installed in accordance with their listed limitations…”

You are confusing PVC (which is not allowed) with listed CPVC (which can be allowed). However, listed CPVC pipes are commercially available up to DN 75 (3"), so it's used in standpipe systems is severely limited.
Thank you for the clarity.
Have a material specifier spec the piping per MasterSpec SECTION 211200 - FIRE-SUPPRESSION STANDPIPES. It makes no sense in experimenting with any different type of piping. Retain a licensed fire protection engineer review the specifications. MasterSpec is a master guide building and construction specification system used within the United States by architects, engineers, landscape architects, and interior designers to express results expected in construction. Just goggle search the MasterSpec 21120 and you will get your answer.
Will do, thank you.
You should not use CPVC in standpipes systems. CPVC is intended for sprinkler systems in "light hazard" occupancies. PVC uses ar limited to underground installations.
